Add the ability to preload the destination GID and LID caches
Preloading of these caches is supported via a file which is
produced by OpenSM by the dump_pr plugin which contains
sufficient SA PathRecord information. Details on this
file format and configuring OpenSM for this are found in
dump_pr_notes.txt in dump_pr.
File format is specified in ibacm_opts.cfg as follows:
path_rec_fmt full_opensm_v1
File format defaults to none which means no preload of ACM cache.
